AUTOMATIC SELF-CLOSING ATTACHMENT FOR WINDOWS.

Specification of Letters Patent.

Application filed November 29, 1912.

Patented Sept. 16,1913. Serial No. 733,927.

To all whom it may concern Be it known that I, EZEKIEL VAN Noon- DEN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Automatic Self-Closing Attachments for Windows, of which the following is a full, clear, and exact description, reference being'had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention relates to a window employing sliding balanced sashes and pertains to an attachment whereby either one or both of these sashes may be automatically closed in case of fire, if open.

The essential object of my invention is to provide an attachment or V arrangement which may be applied to a window of the usual or common construction without necessitating changing the casing of the window or sashes contained therein.

My invention can best be seen and understood by reference to' the drawings in which- Figure 1 is a view partly in front inside elevation and partly in section of a window fitted with the improvement embodying my invention. Fig. 2 is a section on the line 2-2 of Fig. 1, and Fig. 3 is a section on the line 3-3 of Fig. 1. j

Referring to the drawings: 1 represents the, casing inclosing sashes 2 and 3 ofwhich 2 represents the upper sash and 3 the lower sash. These sashes are disposed and arranged to slide vertically in the casing in the usual manner, the casing for this purpose being provided with ways 4 for retaining the sashes. Both sashes are normally balanced sashes, that is, each sash is maintained in a manner whereby it will remain in any open or closed position to which it has been moved. For this purpose the lower sash 2 has attached to it supporting chains 5 which pass upwardly and around pulleys 6 located within the casing and thence downwardly through the interior of the side walls of the casing, and carry balancing weights, 7 or, in other words, weights operating through the chains to hold the sash in a balanced position as aforesaid. The upper sash is supported by means of chains 8 connecting therewith which extend upwardly and around the pulleys 9 and thence downwardly into the interior of the side walls of the casing, and carry upon their ends weights 10. These weights 10 are weights which overbalance the upper sash, or, in other words, are of such mass as will operate to hold the upper sash in a closed position, or close the same if open. To

counterbalance these weights and balance the upper sash it carries weights 11 which together with the sash just counterbalance the welghts 10. The upper sash will accordingly under ordinary conditions be balanced to maintain a closed or open position as desired. The weights. 11, however, op-

erate not only as balancing weights for the upper sash, but are so disposed anclmaintained that in case of fire they will automatically become released from the upper sash to connect with the chains 5 supporting the lower sash and thus combine with the lower sash for closing it by overbalancing the weights 7 which normally counterbalance I this sash.

The weights 11 are disposed and arranged as follows :They are oppositely arranged to lie alongside and adjacent the interior face ;of the top crossbar 12 of'the upper sash lwithin the plane of the lower sash. extend at their outer ends into the adjacent runways 1 of the lower sash or have such extension that the chains 5 supporting the lower sash will pass through the ends of the weights by slots or openings 13 formed therein. The weights 11 are supported by rods 14. These rods are bent rods so as to extend in part under the weights in order that the weights may rest thereon. At their outer ends the rods are pivotally secured to the top crossbar 12 of the upper sash by connections 15 on which the rods may turn and swing downwardly releasing the weights to drop.

For the purpose of maintaining the rods in an upright position for supporting the weights, the inner ends of the rods are loosely socketed or contained in a holder or short sleeve 16. This holder has fixed to itan eye 17 with which connects one end of a fusible link 18. This link is located just adjacent the crossbar of the upper sash inside the window between the weights 11. Connecting with the other end of this link is a hook 19 which extends through the crossbar 12 of the upper sash and is secured thereto by a tab 20 of fusible metal which is located on the outer side or face of the sash outside the window. The weights 11 are further maintained in place upon the When the lower sash is moved the. chain 5.

rods 14 by means of guards 21 fixed to the top crossbar 12 of the upper sash and ex: tending over the weights and embracing the same in the manner of clips.

The operation is as follows: Under ordinary conditions both the upper and lower sashes are balanced sashes and will maintain a closed or open position as occasion may require. The weights 11 will not interfer-e with the movement of either sash.

supporting the same will render through the ends of the weights by the slots or .OPBII'. ings therein. When the upper sash is moved the weights by the openings therein will:-

slip over the chains 5 supporting the lower sash. In case of fire, however, one or the other of the thermostatic connections 18 or QOwill become fused; by the heat, depending 'as the fire is inside or outside of the build:

ing. Thereupon the holder or sleeve 16 no longer retained, will release the rods 14 and the rods will accordingly fall. As the rods fall the ends thereof 'will become disconnected from the holder or sleeve and the weights 11 resting thereon will be released to drop. As the weights drop they will turn with their supporting rods 11, pivotally retained as aforesaid, and thereupon will become attached to the supporting chains 5 of the lower sash by forming a bight therein and accordingly will combine with the lower sash to overbalance its normally counterbalancing weights 7 when the sash if open will become automatically closed. At the same time the upper sash, freed of the weights 11, will automatically become closed, if open,

1 by the weights 10 which, as before described,

are weights which over-balance the upper sash,

Having thus fully described my invention, I claim and desire to secure by Letters Patent ofthe United States 1, In a window, the combination of upper and lower sliding sashes and fixtures 'supporting said sashes, of a releasable weight arie i pate t rear be ob ained 1. 1%

weight to said upper sash, whereby it may automatically become released tjherefrom in case of fire.

2. In a window, the combination with a balanced lower sliding sash and fixture supporting the same, of an upper sash, a releasable'weight carried by said upper sash with an opening therein through which said fixture extends, and means for releasably securing said weight to said upper sash.

3. In a window, the combination With a balanced lower sliding sash and fixture sup: porting the same, of an upper sash, a, releas. able weight having an opening therein Gill ried by said upper sash and arranged wheres.

by said fixture may extend through the. opening in the weight, and means for releasably securing said weightto. said upper sash, whereby it may turn-when released and. form a bight in said fixture for attachingitself thereto.

4:. In a window, the. combination with upper and lower sliding sashes, of a fixture support: ing said lower sash and balancing weight car-. ried by it, a fixture supporting said upper sash, an over-balancing weight carried byfit,

upper sash andloosely cooperatingwith the fixture supportingsaid' lower sash, whereby it may become attached thereto upon a re lease thereof from said upper sash, and

means for securing said weightto said upper sash, whereby it may automatically become released therefrom in case of fire.

5. In a window, the combination with balanced lower sliding sash and fixture sup-.

porting the same, of an upper sash, a weight having an opening in it carried by said u per sash and arranged whereby saidfixture? imay extend through the opening in the iweight, a fixture bearing said weight pivotally secured to said upper sash, and'means connecting with said upper sash for main taining saidpivotedfixturesuppor-ting sai'd' weight in an'operative position, said means comprisingin part a fusible connection,

carried by the upper sash and loosely 'fcooperating with the fixture supporting said 7 lower sash, whereby it may become attached 1 thereto upon a release thereof from said 5 upper sash, and means for securing said i Witnesses:
